Christopher Nolan's blockbuster film "Oppenheimer" largely omits the women and the people of color worked on the real-life Manhattan Project, instead zeroing in on the white men involved in the US government's atomic bomb initiative. Chien-Shiung Wu is a physicist who broke through both gender and racial barriers in 1940s America, wowing the science community with her significant contributions to the Manhattan Project. Wu was born in Jiangsu province, China, on May 31, 1912, to a family of intellectual revolutionaries. Oppenheimer himself reportedly said, "Go invite Ms. Wu - she knows everything about the absorption cross section of neutrons." In his autobiography, prominent Italian physicist Emilio Segrè compares Wu to her heroine Marie Curie, but said Wu was more "worldly, elegant, and witty." Yet, when the movie was made, none of it was even slightly mentioned.
